可降低电磁干扰的串激式马达
摘要：
一种可降低电磁干扰的串激式马达,包括定子,转子,二电刷及印刷电路板。转子包括轴承,设在轴承上的换向器,及设在与换向器相邻的核心线圈,核心线圈与换向器电连接,可转动地设于定子内。二电刷用来将电力传送至换向器,且与换向器弹性地接触。印刷电路板包括滤波电路,用来降低串激式马达的电磁辐射,滤波电路与电刷电连接,且印刷电路板设在电刷上方。当换向器与电刷间发生电弧时,印刷电路板吸收辐射以减少电磁干扰。
摘要（英）：

The motor comprises stator, rotator, two brushes and printed circuit board. The rotator consists of bearing, commutator fit on the bearing and core coil which is adjacent to the commutator. The core oil and commutator which are electric connected together are fir and rotatable in the stator. The two brushes is used to transfer electric power to the commutator and elastic contact with it. The printed circuit board with a filter circuit is used to reduce electromagnetic radiation of series motor, the filter circuit is electrically connected with the brushes on which printed circuit board is fit. The printed circuit board absorbs radiation to reduce electromagnetic interference when arc is generated between the commutator and brushes.
